Fracking causing rise in methane emissions, study finds

Researchers say boom in shale oil and gas major contributor to climate emergency

The boom in the US shale gas and oil may have ignited a significant global spike in methane emissions blamed for accelerating the pace of the climate crisis, according to research.

Scientists at Cornell University have found the "chemical fingerprints" of the rising global methane levels point to shale oil and shale gas as the probable source.
